1919] Howe — Dragon-Flies from Wareham, Mass. 65 



A LIST OF DRAGON-FLIES COLLECTED AT WAREHAM, 

 MASS., DURING THE YEARS 1911 TO 1913 BY MR. 

 OUTRAM BANGS. 



By R. Heber Howe, Jr. 

 Thoreau Museum of Natural History, Concord, Mass. 



The following rather remarkable list of Odonata is the result of 

 my determination of a collection made by Mr. Bangs at Wareham, 

 Massachusetts, and the material on which it is based is now dis- 

 tributed through the general collection of the Museum of Com- 

 parative Zoology, Cambridge, Mass. Access to the specimens was 

 obtained through the kindness of Mr. Nathan Banks, and per- 

 mission to publish the list secured from both Mr. Banks and Dr. 

 Samuel Henshaw. Several duplicates are in the author's col- 

 lection, and that of the Boston Society of Natural History. 



Though Mr. Bangs is not familiar with the group Odonata his 

 trained naturalist's eye made it possible for him to collect a very 

 large percentage of the species that occur, and the list is deficient 

 only in the Zygoptera or smaller Damsel-flies. Mr. Bangs has 

 provided annotations of several interesting species. 



Zygoptera. 



1. Agrion wquabile (Say). "Occurs only, so far as I know, along 



Eagle hill river. I got one." 



2. Agrion maculatum Beauv. June 2-9. Several specimens. 



3. Lestes eurinus Say . June to July 30. Several specimens. 



4. Lestes unguiculatus Hagen. One specimen. 



5. Lestes rectangularis (Say). June 28 to July 30. Several 



specimens. I collected it at Monument Beach. 



6. Lestes vigilax Hagen. July 30. One specimen. I collected 



it at Wareham in 1917. 



7. Lestes inequalis Walsh. Aug. 12. One specimen. 



Note: I collected Lestes forcipatus Rambur., in the nearby town 



of Monument Beach. 

 S. Argia violacea (Hagen). July 5 to Sept. 4. Several specimens. 



I collected it at Wareham in 1917. 

 9. E7iallagma durum (Hagen) June to Aug. 3. Several specimens. 



This is the most northern station for this species.
